Oh how we don't want to be alone in the universe!
I believe there is life on other planets. In this regard, a promising planet is Mars, whose exploration began in 1962 with the launch of the Soviet probe "Mars-1". Since then, the planet has been explored by spacecrafts. But humans have not yet set foot on the Martian surface.
The fact is that it takes seven months to fly to Mars and the same amount of time to fly back. You have to live there too. A ship with life support suplies and fuel is too heavy, it's impossible. That's why we need to invent a machine that can produce the necessary stuff on the spot. I think it will happen soon. I'd like to confirm the belief that there was life on the planet Mars. And this belief comes from a dream in which I saw an ancient man-made observation deck of the Red Planet so real that I do not doubt its existence for a second.
